对应用轻便地震仪进行反射波法测量,以达到圈定岩石界限的效果作了探讨。在加拿大地盾做了5000英尺的工作量,剖面线横过元古代的砾岩和太古代的杂岩的接触界线。在解释方面,由于消除了存在野外记录中的多次反射,分出了深度达1100英尺的反射层。其结果与从露头和钻孔中获得的地质资料的吻合程度比较好。在该面积上应用地震方法的结果表明,它对解决矿产勘探中的构造问题,指明了广泛应用的途径。
The application of portable seismograph reflection wave method to achieve the effect of delineating the boundaries of the rock were discussed. With 5,000 feet of work done at the Canadian Shield, the cross-section lines crossed the boundary of metamorphic conglomerate and archaean complex. In terms of interpretation, a reflection layer of up to 1100 feet deep has been isolated due to the elimination of multiple reflections in the presence of field records. The result is in good agreement with the geological data obtained from outcrops and boreholes. The results of applying the seismic method in this area show that it has pointed out a wide range of approaches to solve the structural problems in mineral exploration.
